M11x Download Driver issues

Ok, well i just bought a m11x, and only have had it for about 2 weeks now. ive been updating all the stuff, installing games, and what not, but on one of my games that i play, "World Of Warcraft" in the graphics options there is a Bar where you can just slide it left to right and it turns your graphics up or down,

example" (___Low___Fair___Medium____Good____Ultra)

but there is a Red bar over Medium, Good, and ultra. only allowing me to turn the graphics up to Fair, and under Liquid Detail, it says i need to update my graphics Driver, so at first i went to Nvida, downloaded theirs, it worked....untill i turned off my computer, when it rebooted everything looked like it was in "safe mode" like the icons were bigger, screan was blury. all that, so i went to Dell's website and redownloaded theirs and everything was better, but the graphics didnt work again. oh when i did download Nvidas everything worked Great till i shut it down. but idk if i maybe have a bad driver, or its just because Dell never updates their drivers. but if anyone has any idea on how i could fix this, please comment or w/e. Thanks.

 

i tried that, didnt work either
